NoN-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Jan. 4, i916.

Application filed February 8,1915. Serial No. 6,728.

yfollowing is a specication.

This invention relates to a closure for bottles and more particularly toa non-refillable type of bottle.

The object of the invention is to provide a closure, for a bottle orlike receptacle, which opens automatically when the bottle is inverted,to allow the free flow and discharge of the liquid contents of thebottle and which also automatically closes when the bottle is beingreturned to its normal upright position, the automatic closing takingplace at a time when the bottle 1s approXimately horizontal and beforethe air could escape if the bottle was submerged in a liquid in anendeavor to refill-it.V

A further object is to'provide a 'closure consisting of few parts soarranged and combined as -to operate in an eliicient and positive mannerto the end desired.

Vith the above and other ob]ects in view, the nature of which will bemore fully understood from the description hereinafter, the inventionconsists in the novel construction of closure for bottles as hereinaftermore fully described and defined in the claims.

Referring to the drawings: Figure 1 represents a sectional elevation ofabottle closure embodying my invention; Fig. 2 represents a. plan ofcertain parts of the device; Fig. 3 represents a side elevation of one part detached; Fig. 4 represents a similar section as Fig. l with theparts turnedso that the contents of the bottle may be discharged.

' 1 designates the'neck of a bottle or like p receptacle for containingliquids, and to the mouth of which the closure of my 'invention isadapted to be secured in a suitable manner. As here shown, the body 2 oftheolosure, which is preferably of glass,- may be cemented to the neckas indicated at 3, and is also provided with an encircling bushing 4 oflcork or other suitable packing material disposed between thecementingmedium and the interior of the.` neck as a safeguard againstleakage by way of the .cement or its joint. Itwill be understood thatthis means of securing the body 2 to the neck is merely one formofavailable construction, as I do to forma discharge outlet for the liquidoontents ofthe bottle and'it alsov serves to guide thestem 6 oftheconical valve piece`7 and maintain the latter in proper operativerelation to its adjuncts.v The stem 6 of the v alve piece is preferablyof fluted construction 1n order that theliquid may flow along the sidepassages thus provided, and with the least frictional resistance tomovement of the valve piece on closing. The outer portion of thepassageway 5 is outwardlv iiared to form a conical seat 8 corresponding1n contour to they conical or truncated Yconguration of the valve piece7, so that in seated position of the valvepiece communicationl by way ofthe passageway 5 is entirely cut ed. The valve piece 7 is preferablyprovided with a rounded top 9 which gives added weight to the end ofthe'valve piece 7 and with it constitutes a weighted head, for a purpose'which will later be eX- plained. 1

The passage way 5 opens into an enlarged chamber, formed by theprojecting circumferential flanged wall of the body 2, which is adaptedto contain a control member 10 for the valve piece 7. This member 10 isprovided with radially disposed lugs 11 `which seat within suitablenotches formedl in thecap 12, whereby cementing of the cap to the body 2permanently iiXes the member '10 in its operative position. l

14 formed bythe spacedV lugs, into the cap chamber whereby it may bedischarged lthrough the outlet 15. As here shown, theoutercircumferential-edge o-f the/.outlet 15 is providedv with a small bead164 to form a tight contact joint with the cork filler or lining 17 ofthe metal closure cap 18. 'Ihe cap 12 is provided with the annularundercut groove 21 near its outer part to form a' shoulder over Awhichthe' perimeter of the loo los

metal closure 18 may be clamped. This closure 17, 18 may be of any wellknown construction suitable for sealing the discharge outlet until it isdesired to make use of the liquid contents. Vhen the closure 18 isremoved, the bottle may be sealed with an ordinary cork stopper, and itis manifest that such a stopper may be used in place of the closure 18,if so desired.

n connection with the cupped construction of the member 10, it will benoted that the outer portion of its inner circumferential wall isdownwardly and outwardly flared in order to provide an incline, incertain positions of the bottle, upon which the relatively sharp edge 20of the valve piece is adapt-ed to rest and slide under the action ofgravity. This action takes place more particularly when the bottle neckis substantially horizontal or inclined to the -hori zontal when theneck is raised after a discharging operation.

As the valve piece head portion is circular the edge 2O is a circle, andas its diameter is less than the diameter of the space formed betweenthe opposite walls and lugs of the member 10, it follows that the actualcontact is har lly more than a point and hence produces very littlefriction.

1n the position indicated in Fig. l the bottle neck is supposed to bereturinig to its normal upright position, after a quantity of liquid hasbeen discharged; and it will be seen that the effective action of theincline portion 19 is coming into operation. Consequently the weightedvalve piece head is guided down the inclined surface and as the neckcontinues its upward movement the valve piece and stem are guidedquickly and accurately to their normal position to close the passage 5.It will be noted that the inclined surface 19 is quite steep where thevalve edge 20 rests upon it in Fig. 4l, and consequently the weightedhead exerts considerable tendency to slide down; this impetus given tothe rest of the valve piece will, as the incline of the surface 19decreases, cause the valve piece to be shot into its seat to seal thebottle before it can assume a position which could permit the inflow ofliquidand outflow of air, if attempts were made to refill it.

It will be manifest that the essential feature of this invention is inproviding the valve and valve seat with means which will shield itagainst being tampered with, and at the same time will provide apropelling action to the valve piece under the action of gravity, whenthe body is approximately in a horizontal position; and while I havedescribed a construction which believe is most preferable, on account ofthe commercial making and assemblage of the parts, both from aneffective and economical point of view, I do not in any manner restrictmyself to the detailed construction of the elements making up thedevice. While the member l0 acts to provide the inclined guidewayfor theweighted head of the valve piece, it also provides a shield between theoutlet 15 and the valve piece to prevent the insertion of any wire orinstrument to hold the valve piece in open position or votherwisetampering with it. While I have shown the members 10 and 12 as madeIseparate and connected together in the assemblage of the closure as awhole, it is manifest that the making of these parts in separate pieces,instead of one piece, is merely to overcome the difliculties of moldingor otherwise forming them, especially as it is desirable that they shallbe made of glass or refractory material which will take Va high finish,and thereby eliminate as much as possible friction between the operativeparts. it will be understood that these parts may be made in one pieceif that were conveniently and economically possible, such as if theparts were molded from metal, but l prefer to use vitreous substances,such as glass, for obvious reasons, and in those cases it is notconveniently possible to mold intricate structures providing channelssuch as 111-. l therefore do not confine myself to the manner of makingand assembling` the several parts 2, 10 and 1Q, so long as they bear afixed relation to each other and provide a seat for the valve pieceassociated with the necessary fluid passages, and also provide the camvor inclined surface 19 for the operation of the valve piece, ashereinbefore described.

ln the construction here illustrated, the body Q, member 10 and the cap12 are all preferably of glass or like material, cemented or similarlyconnected together to form a complete unitary structure. The partstherefore provide smooth surfaces for the passage of the liquid contentsand insure the desired sanitary condition necessary in an article ofthis kind.

It will now be apparent that l have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable, and while l have in the present instance shown and describedthe preferred embodiment thereof which has been found in practice togive satisfactory and reliable results, it is to be understood that l donot restrict myself to the details, as the same are susceptible ofmodification in various particulars without departing from the spirit orscope of the invention.

Having now described my invention, what l claim as new and desire toprotect by Letters Patent is:
